in peril--in
deadly peril!"

"How?" I exclaimed breathlessly, surprised at his extraordinary change
of manner and his evident apprehension lest something should befall me.

"Wait, and you shall see," he whispered. "But first tell me, signore,
that you will forgive me for the part I have played in this dastardly
affair. I, like yourself, fell innocently into the hands of your
enemies."

"My enemies! Who are they?"

"They are unknown, and for the present must remain so. But if you doubt
your peril, watch--" and taking the rusty fire-tongs from the grate he
carefully placed them on end in front of the deep old armchair in which
I had sat, and then allowed them to fall against the edge of the seat,
springing quickly back as he did so.

In an instant a bright blue flash shot through the place, and the irons
fell aside, fused and twisted out of all recognition.

I stood aghast, utterly unable for the moment to sufficiently realize
how narrowly I had escaped death.

"Look! See here, behind!" cried the Italian, directing my attention to
the back legs of the chair, where, on bending with the lamp, I saw, to

"Your enemies prepared this terrible trap for you," declared the man who
was once my trusted servant. "When I entered into the affair I was not
aware that it was to be fatal. They gave me no inkling of their
dastardly intention. But there is no time to admit of explanations now,
signore," he added breathlessly, in a low desperate voice. "Say that you
will not prejudge me," he pleaded earnestly.

"I will not prejudge you until I've heard your explanation," I said. "I
certainly owe my life to you to-night."

"Then quick! Fly from this house this instant. If you are stopped, then
use your revolver. Don't hesitate. In a moment they will be here upon
you."

"But who are they, Olinto? You must te
